It's not the first time I've written about food waste and it won't be the last. Too many of us toss edibles that are wonderful ingredients--beet, radish, and carrot tops; vegetable scraps; animal parts that don't conform with popular cuts or filets. It's costly and unsustainable on many levels. Local chefs are very aware of this and the two I write about in this San Diego Union-Tribune story--Miguel Valdez of The Red Door and Rob Ruiz of The Land and Water Company--have been conscious of it for years and are participating in Re:Source, a 2016 event featuring chefs and restaurants demonstrating how to use ingredients sustainably. Learn how you can turn carrot tops into pesto and odds and ends of veggies into a sumptuous gazpacho.
